The lounge name in Traveloka not clear enough, there are two lounge in T3 one is blue sky and other is plaza premium. This one is Blue Sky, so don't expect much. The process booking check-in is slow, and not very welcoming attitude.
The atmosphere of the lounge are not comfort at all, everything is narrow. That's because the space really small I think.
The choice and spread of food is limited and replenish process very slow. I would better pay for coffee shop nearby and having a rest there.
